I can receive e-mails to my home using office server.
However when I send e-mails from home to anyone else
(apart from me at the above address) I get the following
message: 553 sorry, that domain isn't in my list of
allowed rcpthosts (#5.7.1)
The computer allows me to send e-mails back to the above
address so I can re-open them in the morning at work but
thats it.
What do I do to get this to recognise these e-mail
addresses!
 
Apparently you are not using a VPN (virtual private network) to connect
to your company's network. Instead it looks like you are connecting to
your company's server by going through your ISP and across the Internet
"in the open" to connect to their server as you would with other POP3
servers. Since you authenticate to that POP3 server you can yank your
e-mails from there. You may also have to authenticate to your company's
SMTP server to send e-mails. That's because you are no longer on their
network and so their SMTP server won't know who you are unless you
authenticate to it. You can configure Outlook to reuse the same
username and password as configured for the POP3 server or have it use
separate username and password (which may be the same or different than
for their POP3 server).

However, you are trying to connect to your company's SMTP server across
your home ISP's network. Unless you get special permission from your
ISP to do so (which usually means you have to get a static IP address),
they probably will refuse to relay SMTP traffic across their domain.
That's to prevent spammers from abusing their network to use some SMTP
server on a different network, or to allow some spammer from a different
network to abuse their SMTP servers. Relaying SMTP traffic is usually
bad Netiquette. In that case, you must configure the SMTP server in
your e-mail account to use your ISP's SMTP server, not your company's
SMTP server. So your e-mail account would have:

POP3 server = pop3.mycompany.com
SMTP server = smtp.myisp.com

The above are only figurative examples of the server names. You will
have to substitute your company's POP3 server and your ISP's SMTP server
in the appropriate fields.
 
You need to turn on authentication to your outgoing server. You can do
so on the "Outgoing Server" tab for your mail account.
